UPDATE 2-Israeli missiles hit near Damascus Airport - SANA, monitor

CAIRO, June 26 (Reuters) - Syrian state news agency SANA said two Israeli missiles hit in the vicinity of Damascus international airport in the early hours of Tuesday morning, without giving further details.

The Syrian Observatory for Human Rights war monitor said Syrian air defence systems failed to intercept the missiles.

The Britain-based war monitor said an explosion was heard at 1 a.m. (2200 GMT Monday) near the airport, caused by missiles fired by Israeli planes from the direction of the Golan Heights.

"It targeted weapons depots and warehouses belonging to non-Syrian militias loyal to the (Syrian) regime," the observatory said, adding it had no information about casualties or damage.

Asked about the report, an Israeli military spokesman said: "We do not comment on foreign reports." (Reporting by Nayera Abdullah in Cairo and Lisa Barrington in Beirut; editing by Diane Craft, Stephen Coates and Michael Perry)
